[jira] [Created] (CALCITE-5238) Add a maxNodeCount parameter to RexUtil.toDnf

Yingyu Wang created CALCITE-5238:
------------------------------------

             Summary: Add a maxNodeCount parameter to RexUtil.toDnf
                 Key: CALCITE-5238
                 URL: https://issues.apache.org/jira/browse/CALCITE-5238
             Project: Calcite
          Issue Type: Improvement
            Reporter: Yingyu Wang


This is similar to CALCITE-1290. Add a {{maxNodeCount}} parameter to {{RexUtil.toDnf.}} If the number of resulting nodes exceeds that threshold, stops conversion and returns the original expression. Negative number means no threshold.
